IPC: H03K17/00
Filed: 1982-06-30
Abstract: PURPOSE:To send a specified output to a fail-safe side even when abnormality is caused by noise, by improving partially an input signal, stopping output operation temporarily by the coupling of one-shot timers, and sending out the specified output after switching. CONSTITUTION:When an input terminal 12 is at a level H and an input terminal 11 is at L, signals L(19a) and H(21a) are outputted to input confirmation terminals 19 and 21, but when the input is so improved that lap signals (T11-T12) are inputted during input switching, those lap signals are detected by the one- shot timers 15 and 22. The timer 22 detects H-to-L transition as a signal 22a and the level L is held for a time Ta. Then, the timer 22 detects L-to-H transition (T12) as a signal 22a and the level L is held for the time Ta from T12. Then, an NAND element 132 and an inverter element 141 sums up the levels L of the signals 15a and 22a to send the resulting signal to gate elements 133 and 135 as gate signals, so that normal signals appear at the input signal confirmation terminals 19 and 21. If two inputs in case of a fault T13 of the input signal are supplied, input abnormality is permitted for the timer time Tb of a timer 16 from T14 and when the fault continues for longer than it, an abnormality output 20 is sent out.
